For the reciprocal of a number, enter the number then press the key marked with an x^-1. You might have to use the SHIFT key first. For inverse of trigonometric functions use the SHIFT key followed by the function name. The inverse of LN is e^x. The inverse of log is 10^x. To calculate the inverse of a matrix, enter the name of the (already created) square matrix then press x^-1.
Antilog is a somewhat outdated terminology for the inverse function of the logarithm. To calculate on your FX-300ES the base 2 antilog of 4, key in Correct result is 16.
Antilog is a somewhat outdated terminology for the inverse function of the logarithm. To calculate on your FX-115ES the base 2 antilog of 4, key in Correct result is 16.
The inverse of the log function is the function 10^ antilogarithm of (x)=10^(x) The function shares the same physical key as the [LOG] function. To access it you press [SHIFT][LOG].
The antilogarithm of the natural log [LN] is the exponential function [e^x]. It shares the same physical key with the [LN] function. To access it press [SHIFT][LN]
Hello, 1.Set the correct angle unit required by your problem: degrees, radians, or grads. [SHIFT][MODE] [3:deg] or [4:Rad]
2. Press the key for the function COS, SIN, or TAN [COS] displays Cos(
3.Enter the angle 12 deg Screen shows cos(12 Close the right parenthesis ) Screen shows cos(12) 4.Press [=] Screen displays 0.9781
If you want the inverse trigonometric functions you access them with arccos [SHIFT] [COS] (cos^-1) arcsin [SHIFT][SIN] (sin^-1) actan [SHIFT][TAN] (tan^-1)
You have to know the principal domain for the inverse trigonometric functions (see any book on trigonometry) to understand the results. Hope it helps.
